INTERROC is the world's most
versatile
model rocket. Includes "Interchangable Motor Mounts-tm" to allow
several motor
combinations to be prepared in advance for "quick change"-sm at the
launch site!
Interroc is the first high power / model rocket with this unique
and handy
feature. The main mount or airframe tube is called the "Host
Mount". Different
motor mount assemblies slide in and are held in place using the
same system as
the motors themselves. The kit includes mounts for three 24mm
motors and single 29mm
motors. Try three D12-7, three E12-8, three E25-8, three F25-8
or single F20-8, G30-8, G60-8.

INTERROC
can be slightly modified to
accept new dual deployment systems and altimeters. The payload
can be deployed on both sides of
the coupler or both sides of the payload tube. Its stable
design makes it suitable for
drop-staging (CHAD) and for affixing glider mounts for test
flights of those competition
gliders.
This rocket is recomended for schools, recreation programs and
science work. It can fly on as
little as C6-3 and flies surprisingly well on D12-5 or D12-0 to
D12-5. Best flights are with
USR
F20-8. INTERROC has been successfully tested with as high of
power as J125-12 and as high
thrust
as H320-12. Its very strong and lightweight construction makes
it fly surprisingly high
compared
to other rocket kit brands. Test it for yourself!
